What's an Adventitious Root

Adventitious roots are plant roots that form from any nonroot tissue and are produced both during normal development (crown roots on cereals and nodal roots on strawberry [Fragaria spp.]) and in response to stress conditions, such as flooding, nutrient deprivation, and wounding.

What does adventitious root mean?

Definition of adventitious root : a root that arises from any point other than the radicle or the root axis (as the prop roots of corn arising from the lower stem) — compare aerial root.

What are adventitious roots also called?

Some roots, called adventitious roots, arise from an organ other than the root—usually a stem, sometimes a leaf. They are especially numerous on underground stems, such as rhizomes, corms, and tubers, and make it possible to vegetatively propagate many plants from stem or leaf cuttings.
